Video: Visitors’ Voices Gathered at Sept. 11 Memorial Museum

Tucked inside the National September 11 Memorial Museum is a video recording booth. Here, the museum, which opens next week, hopes to gather the voices of visitors, reflecting on how the terrorist attacks affected their lives, and how the world has changed since that day.

The visitor responses will be projected alongside those of people including Billy Crystal, Donald Rumsfeld, Hillary Clinton and others, in an exhibit called “Reflecting on 9/11.”

One emotional response comes from Howard Lutnick, chairman and chief executive of Cantor Fitzgerald, who lost 658 colleagues that day, including his brother, Gary Lutnick.

He describes the most important lesson he learned from the terrorist attacks: “The people you work with, while you may not say it, matter so very much to your life,” he says, his voice cracking. “Because if they were all gone – your workplace was gone and everybody you worked with was killed – you would cry just like I did, because we loved them.”
